ABSTRACT:
A filter for a pulse form of signal which substantially reduces sidebands, yet provides an output signal which is substantially free of jitter and at the same time has no inter-symbol interference. The filter comprises means for detecting the pulse type of signal and for substituting .pi. radians of a sine wave signal with a positive slope upon detection of a positive going leading edge of the pulse type signal and .pi. radians of a sine wave signal with a negative slope upon detection of a negative going trailing edge of the pulse type signal, at an output terminal.
